[Production of enzyme preparations on the basis of Penicillum canescens recombinant strains with a high ability for the hydrolysis of plant materials].


PMID 22567887

Abstract

An enzyme preparation has been produced on the basis of Penicillium canescens strains with the activity of cellibiohydrolase I, II; endo-1,4-beta-gluconase of Penicillium verruculosum; and beta-glucosidase of Aspergillus niger. It was shown that for the most effective hydrolysis of aspen wood pulp the optimal ratio of cellobiohydrolase and endo- 1,4-3-gluconase in enzyme preparations was 8 : 2 (by protein). It was also established that the homologous xylanase secreted by the Penicillium canescens fungus is a required component for the enzyme complex for hydrolysis of the hemicellulose matrix of aspen wood.
